• Build, align, and characterize optical laboratory setups and optical subsystems.

• Support testing and validation of optical components and subsystems, including lenses, windows, mirrors, lasers, detectors, and related opto-mechanical assemblies.

• Perform optical alignment tasks including free-space alignment, beam collimation, focusing, and optimization of optical paths.

• Execute optical characterization and system-level test procedures and analyze the resulting data.

• Develop Python scripts for instrument control, test automation, data processing, visualization, and analysis.

• Assist with development and validation new sensor prototyping and manufacturing processes.

• Support optical subsystem bring-up, integration, validation, and troubleshooting.

• Investigate unexpected system behavior using experimental data and fundamental engineering principles.

• Perform measurements and characterization of optical performance, including beam profile, M², wavefront error (WFE), and other relevant optical metrics.

• Work with cross-functional engineering teams, including electrical, firmware, DSP, software, and mechanical engineering.

• Document experimental setups, procedures, results, and conclusions clearly.

• Participate in failure analysis and root-cause investigations with experienced engineers.

• Propose improvements to optical setups, test methods, automation, and measurement techniques.

Required Qualifications
